FBM233 Foxboro P0926GX 10/100 MBPS ETHERNET, REDUNDANT-Colletplc

Description:

Each FBM233 module has a single 10/100Mbps

copper Ethernet connection and a single RJ-45
connector on the front of the module for connectivity
to dual-ported Ethernet devices. The FBM233 is
connected to Ethernet switches or hubs in order to
communicate with one external device or up to 64
external devices.
A pair of modules combine to provide redundancy at
the Fieldbus Module (FBM) level. In this configuration,
one FBM233 is the Master, and the other is the
Tracker module. Input points on the control station
are updated from the device inputs received on the
PSS 21H-2Z33 B4

network connected to the Master. Device output
points, depending on the I/O driver, are written by
both the Master and Tracker module. Role switching
is automatic if problems are detected (for example,
loss of heartbeat from any device) by the I/O driver,
or the user can switch the roles at any time via
SMDH. The general network configuration is shown
in Figure 1.
I/O DRIVERS
This FBM is a generic Ethernet hardware module in
which different software drivers can be loaded. These
drivers configure the FBM to recognize a particular
protocol used by the device. Several of these
software drivers are a standard product offerings.
Other custom drivers can be developed to meet
specific needs. These drivers are dynamically
downloaded to the FBM233 with software code
specifically designed to interface with the third party
device’s protocol.
The configuration procedures and the software
requirements for each driver are unique to the
device(s) being integrated into the system.
ETHERNET LINK SETUP
Data communication between the FBM233 and field
devices are through the RJ-45 connector located on
the front of the FBM233 module. The RJ-45
connector of the FBM233 can be connected through
hubs, or through Ethernet switches to the field
devices (refer to “ETHERNET HUBS AND
SWITCHES” on page 7). The FBM233 is connected
to Ethernet switches or hubs in order to
communicate with one external device or up to 64
external devices
